Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to a transformer with a passive noise reduction function. Background Art

[0002] Transformers are key power transmission and conversion equipment in power systems and are widely used in power, industrial control, and civil applications. As industry and society increase their requirements for power equipment efficiency and environmental protection, some problems in the operation of traditional transformers have gradually attracted attention, including low heat dissipation efficiency, high noise, high energy loss, and short equipment life.

[0003] At present, conventional transformers generally use ordinary silicon steel sheets as core materials. Their designs often have problems such as insufficient structural compactness and high eddy current losses, which lead to severe heating of the core and uneven heat dissipation, thus affecting the operating efficiency and reliability of the transformer. In addition, since the core and windings generate vibration and electromagnetic noise during operation, conventional transformers often make a lot of noise during operation, making it difficult to meet the requirements for silent operation in modern industrial equipment and residential areas.

[0004] On the other hand, the cooling system design of the transformer also directly affects the performance and life of the equipment. Traditional cooling designs mostly rely on a single fan or a simple ventilation structure, which has limited cooling efficiency and is prone to generate loud noise during air flow. In addition, with the diversification of the use environment, the requirements for heat resistance, corrosion resistance and long-term operation stability of the transformer are also constantly increasing. However, in the existing technology, the overall design scheme for improving heat dissipation performance, reducing noise and increasing equipment life still has certain shortcomings.

The silicon steel sheets 10 are all fixed on a fixing ring, which is a ceramic ring 8, and the silicon steel sheets 10 are pasted on the fixing ring.

[0023] The main body is provided with a plurality of first through holes 9 and second through holes 11 for enhancing heat dissipation and reducing eddy currents.
